Meher,
Attached the SPRUE36 document from TI, where I found the description of
the maximum payload size of 1024 byte for high speed transfers. But I'm
not sure if this short description means, that two or three transaction
per microframe are allowed.
In addition, it says that the wMaxPacketSize field of the Standard
Endpoint Descriptor for the associated endpoint should match the value
written in this register. But I set the value of wMaxPAcketSize to
0x1400 to implement three transactions per microframe.

Patrik,
As much as I know about USB controller used on davinci, it does
not support multiple ISO transfers per frame. The description above
states that you can send maximum payload of 1024 bytes in a single
transfer.
Take also a look at the section
4.47 Power Management Register (POWER)
on page 124
regards,
Patrik
